MP2510 dots on copies

[leo34staffs]

Hi Guys,

We have a lot of these machines out and although they are based on previous models, (even the same pcu fits) we keep getting spots on copies from dinks in the drum, is it just our customers or has any one else found this?

Can't say I've seen any of our MP2510/3010 suffer from dinks on the drum.
I have seen the friction of a new cleaning blade damage a drum though, it's important to applied some toner to the edge of the blade to help run it in.

We have a spare PCU we rebuild back at the workshop.
That fits the Aficio 3025/3030/MP2510/MP3010 and I have a feeling it may also fit the new MP2550/3350 as well (but I've not tried yet).

All those models use the same toner, developer and drum.

/DaZ wonders if a older DMU23's will even fit and work.

[leo34staffs]

hey up Daz, yes the drum that fits the 1022/2022 fits this machine (as long as you turn off the new drum detection off in the sp mode. That way its a lot quicker to replace the unit oppossed to replacing drum/dev etc.

[Cipher]

Hmmm interesting, I thought that a DMU23 may work but I never got around to trying one.

Have you looked into the cost difference between replacing a DMU23 and replacing the PM parts? is there much difference?

[leo34staffs]

hi Daz , im not sure about cost difference, but from a time perspective, its quicker. The only reason we fitted one in the first place was an oversight on our part, we thought this WAS the right pcu for this model. We fitted it and got an error, then our supplier said there engineers disabled the pcu check and it worked (cant say who that is though lol)

I never deal with costing but im sure its cost effective.

Cheers Leo.

I have had two drums get a mark in when fitted when checked its a mark on the drum. Seem to be very fragile never had the same problem with similair drums.

We have some customers who prefer the pcu and means we quite often dont need to vist just to service a drum unit which has fragile gears, easy to dent drums and seals which seem to damage after a few toners have been changed.

We looked at the costings today and the DMU23 is roughly double the price of changing all the PCU PM parts (including a 1/2 hours labour).

So the most cost effective method for us to keep swapping out the PCU onsite
and PM the one we take out back at the workshop then put it back in stock.

But still it's handy to know we can use a DMU23 if we get stuck waiting for parts.

We send out PCUs to these machines for the customer to replace, they then get a return label to send back the old PCU to our head office for refurbishment.

In the case of many customers this is a good idea that works well and cuts down on the need for site visits.....

....but then you get the other customers where it is sheer madness to the point where you might as well burn money.

I carry one set of the main PCU items (drum, blade, brush, charge roller) and a bag o' dev for the c1 (Aficio 220/270) and the others (1022, 2022 MP2010 etc etc), but I can't remember the last time I actually used them.

I only tend to PM a PCU either when the customer cannot be trusted to change one without damaging the machine or the unit, or the customer has ignored the "replace photoconductor unit" for so long that the copy quality is beyond abysmal and aren't prepared to wait two-three working days for a unit to arrive (whether this is chargeable or not depends on their attitude, as it is their fault and they are responsible for notifying us when they need consumables it is technically a chargeable call to PM a PCU onsite, if they are nice then I let it slide, if not they get a bill)

I've gone about doing drums like this: I use a 1022/1027 PCU when a 25/30 needs one and then rebuild the PCU in the office and the next call for one gets the rebuilt PCU. The problem with rebuilding the PCU like paulg alluded to are the dev gears seem to get shredded and the seals seem to wear by just looking at them. The only difference I can see between the 480-0069 PCU and the newer PCU seems to be the face plate (the gear that lets the older versions of the family to know a new PCU is installed) and a few springs on the old 22/27 PCU. The cost difference seems to just be Ricoh milking as much out of customers as they can.
Is it just me though or does the copy quality seem to get a whole lot better when using the 1022 PCU though?

I think the CQ on the 1027 pcu is better than the rebuildable units also.

I've had a few of the B205/B209's chew up multiple new style dev. units and in some cases PCU's. We're to the point that we replace with a new style dev unit and then with the 1027 PCU if problems continue. Some of them work fine with a new style dev unit though. Anyone else seen this too?

[Cipher]

The only problem I remember having on one of these PCUs is when a colleague of mine did not re-attahced the top of the dev unit properly.

Which resulted in a low pitch humming sound.

Apart from that they all having been reaching yield or there abouts.

The strange thing to me is the AF1018 pcus seem far more realiable as the 3025 onward pcus.
It cant just be a speed thing or volume as some of our mp2500's do less than our hardest working AF1018's.

While the pcus on the AF1018's are the same apart from the PM items, most of the 3025's have been modded out of sight.

One thing i must add is make sure you turn of the pcu alarm otherwise at 60 k when fingers crossed they are running ok. Your end up with a call for no reason in many cases.

Ok I had my first PCU with knackered dev gears today.

It's looks like the small plastic gears were simply worn down by to much torque/friction.
I've replaced the damaged gears and put a tiny amount of grease around each one just to see if that helps them last.
